In addition, reservoir releases in all types of reservoirs Lakes, Rule Curve and Pool Allocation can be controlled for flood mitigation by one or more outlets for each connected node.
Simulate reservoir sedimentation While not considered a sediment transport model, users can still route sediment through a river network and calculate the potential deposits of sediment in the reservoirs using a specialised Reservoir Sedimentation module.
Use the APIs to embed the engine into your own code or decision support system. Prioritise water allocation The Global Ranking feature provides users with the ability to prioritise water allocation to water users, hydropower plants and reservoirs independently of their geographical location in the river basin. Simulate rainfall runoff With the Rainfall-Runoff module , you can accurately calculate total runoff surface flow in addition to its percolation to groundwater.
Autocal provides users with easy to use auto-calibration tools to save time when configuring your Rainfall-Runoff model. Represent surface-groundwater interaction at the basin scale Represent the important interaction of groundwater and surface water in the Basin by accounting for groundwater recharge, groundwater discharge, seepage from irrigation fields, rivers, reservoirs and canals and impacts of groundwater pumping on the groundwater levels and river flows.
Perform water quality simulations Water quality simulations can be run using standard, predefined MIKE ECO Lab templates or adjusted to user-defined templates for custom water quality models.
Determine catchment pollutant concentrations Using the Load Calculator , you can determine the amount of pollutants absorbed in the flow paths through catchments and groundwater towards a river network. Specify different pollutant sources related to farming, agriculture, or industrial activities including animal or human waste, sewage sources or fertiliser.
Users can also model distance specific decay or the retention of pollutants. It can be customised to suit individual preferences and requirements and offers a variety of configuration options.
For example, you can visualise background maps e. Google Maps , background layers shape files, raster and images as well as Digital Elevation Models. Analyse results with ease The detailed outputs from MIKE HYDRO Basin offer an easy-to-understand overview of scenario results, such as water usage, water allocation deficit, generated power, reservoir releases, water losses and mass balance.
In situations where you need to check model results against measurements made downstream, users can create calibration plots at any point in a river network.

Map-based modelling for integrated water resources management. Analyse alternative designs and management policies to improve the performance of integrated river basin systems with this versatile decision support tool. Find out more. Quickly establish an easy-to-understand water usage model of your basin. Forget about having to import bathymetric river data.
Delineate rivers and catchments from a digital elevation model in one-click. Analyse availability, use and regulation of your water resources. Support the delicate balance between water availability and demand by creating large-scale, multi-year simulations. This allows users to incorporate runoff from ungauged catchments, assess aquifer recharge, evaluate climate change impacts and analyse performance of proposed or existing infrastructure.
Make real-time decisions to support dam operations and flood mitigation. Predict inflows, improve flood operation management and plan production and releases during the coming hours, days and seasons to optimise reservoir operations and hydropower decision-making.
Water Resources Planners and Managers. Perform climate change impact assessments, investigate alternatives and explore conjunctive groundwater and surface water usage to address water allocation and shortage concerns. Reservoir Operation and Hydropower Managers. Optimise reservoir and hydropower operations to improve energy production and flood operations through real-time decision support for short-term as well as long-term horizons.
Irrigation Managers. Both the natural river system and the water supply network can be modelled. River regulation, forecasting, travel times, the ability to include and calibrate hydrological models and the differentiation of river flow at any point into its 'natural', 'cumulative abstraction' and 'release' components are some of the features available on river networks.
On the supply side, water is used to meet demand using a proven algorithm that seeks to minimise cost, but preserve the state of resources. This means that Aquator can model complicated licensing, catchment transfers and sophisticated reservoir rules more accurately than other packages. Aquator itself can also be built into other applications to provide the water resources input.
Identify the problem to be solved and performance metrics for decision making. Use the network to show how water flows between reservoirs, withdrawers, dischargers, streams, pipes, aqueducts, and other locations of interest. Use model logic to describe current, past, or proposed future water actions by emulating the effects of human-controlled actions at predetermined time intervals. Logic controls how much water is transferred from one node to another at each time step, while also enforcing priorities and limits on uses.
Apply the model to simulate the impact of changes to the system in order to develop solutions to the problems posed in Step 1. The flexibility of the model allows for an array of possible applications, including some that may not have been anticipated beforehand. The model uses inflow and demand data along with usage rules to route water through the system and is intended to be used for long-term planning, short-term operational planning, and regional or local planning. Long-term projections were used most recently in the Colorado River Basin Study that examined potential alternatives to mitigate projected future gaps in supply and demand through These models were developed with an understanding that local management of river processes was imperfect — that a bigger picture, holistic view was needed for effective management.
Over time, these physical systems were represented with electrical analogs, then with resistors and capacitors, equations, and ultimately with computer software. As computer power increased over time, the level of detail and sophistication of models advanced. Basin water supply models are designed to simulate how storage and flow in networks of reservoirs and streams vary over time—from days to decades—using observed or proposed withdrawals by water users, return flows by dischargers, reservoir operations and evaporation losses, inter-basin transfers, and any other human or natural process that impacts the basin water balance.
These models are used to evaluate the system-wide impacts of local water decisions and use on availability, water quality, and other criteria basin-wide. They are often used to support basin-wide regulatory planning and permitting, resolve disputes among water users, inform environmental impact assessments, detect supply risk due to drought, and evaluate future operational and structural options for improving supply reliability.
Basin water supply models are typically developed through several common tasks, illustrated in the slideshow above.
